Summary of Invasiveness

Top of page

T. ulmifolia is a small herb or sub-shrub with a wide geographic distribution. This species has been frequently introduced to be used as an ornamental and medicinal herb. It has escaped from cultivation, becoming widely naturalized in tropical and subtropical regions where it grows as a weed (Smith, 1981; Barrett and Shore; 1987; Wagner et al., 1999). T. ulmifolia appears to be adaptable to a great variety of soil and environmental conditions and this adaptability may explain its success in colonizing new habitats (Gilman, 2011). Currently, it is listed as invasive in Australia, Hawaii, Puerto Rico, the Virgin Islands, Singapore, Malaysia, Indonesia, and on several islands in the Pacific Ocean (Chong et al., 2009; Queensland Department of Primary Industries and Fisheries, 2011; PIER, 2014; Rojas-Sandoval and Acevedo-Rodriguez, 2014). Invasiveness in T.ulmifolia is mostly explained by the continuous year-round flowering that gives its populations a high reproductive capacity. Seed dispersal in this species is by ants which transport seeds relatively short distances. This local seed dispersion favours the establishment of dense populations and increases the likelihood of seed set in this species (Barrett, 1978; Barrett and Shore, 1987).

Notes on Taxonomy and Nomenclature

Top of page

Turneraceae is a family of flowering plants consisting of just over 200 species in 10 genera. The Cronquist system placed the Turneracids in the order Violales, but this is not currently recognized as a valid family by the Angiosperm Phylogeny Group in the APG III system of 2009, which includes the taxa in the Turneraceae in a widely circumscribed Passifloraceae. The taxonomic tree in this datasheet reflects the CAB Thesaurus, which currently uses the Cronquist system.

The bulk of the species in the Turneraceae occur in just two genera: Turnera with approximately 143 species and Piriquetia with 44 species (Shore et al., 2006). Turnera ulmifolia is a polymorphic polyploid complex of herbaceous, perennial weeds, exhibiting two contrasting patterns of floral morphology, where populations are either dimorphic or monomorphic for a range of floral traits (i.e., style length, stamen height, pollen size; Barrett and Shore, 1987; Cuautle and Rico-Gray, 2003).

Description

Top of page

T. ulmifolia is a shrubby or herbaceous perennial, up to 1.2 m tall, with aromatic and densely strigose foliage. Leaves clustered toward the tips of the branches, lanceolate to oblong-lanceolate or narrowly elliptic, 4-1× 2-3 (-5) cm, moderately to occasionally sparsely strigillose, margins doubly serrate, petioles 0.8-1.5 cm long, stipules erect, triangular, approximately 1.5 mm long. Calyx approximately 20 mm long, the tube 5-8 mm long, the lobes lanceolate, apex caudate; petals yellow, sometimes with a brown spot toward base, obovate, 20-35 mm long; ovary ovoid, with 6 small apical tubercles. Capsules ovoid, 7-8 mm long. Seeds narrowly obovoid, slightly curved, about 2.5 mm long (Liogier, 1997; Wagner et al., 1999).

History of Introduction and Spread

Top of page

T. ulmifolia has been widely introduced to be used as an ornamental and medicinal herb. In Puerto Rico, this species was first reported in 1881 (Bello, 1881). In the Virgin Islands it was first collected in 1882 on the island of St Thomas (US National Herbarium). By 1948, it has been reported as “abundant” in Malaysia and Indonesia (Steenis, 1948-1954). T. ulmifolia has been reported as an environmental weed becoming widely naturalized in northern Australia, Western Australia, the Northern Territory, and northern Queensland (Queensland Department of Primary Industries and Fisheries, 2011). 

Habitat

Top of page

T. ulmifolia grows in coastal areas, sandy fields, roadsides, disturbed sites and abandoned farms (PROTA, 2014). In Hawaii, it has naturalized in dry, disturbed areas, from 30-190 m (Wagner et al., 1999). In Fiji, it is locally abundant and can be found naturalized especially in coconut plantations near sea level (Smith, 1981). In Indonesia, it grows in sunny dry localities, at elevation from 1-20 m, especially in the coastal zone under coconuts (Steenis, 1948-1954). In Puerto Rico and the Virgin Islands, it grows in coastal areas, sandy fields, hillsides and waste ground at lower and middle elevations (Liogier, 1997).

Biology and Ecology

Top of page

Genetics

T. ulmifolia constitutes a polyploid complex with allopolyploid and autopolyploid species ranging from 2x to 8x (López et al., 2011).

Reproductive Biology

Two contrasting patterns of floral morphology have been reported for T. ulmifolia populations. Populations are either dimorphic or monomorphic for a range of floral traits (i.e., style length, stamen height, and pollen size) associated with the breeding system. Dimorphic populations exhibit typical features of the distylous genetic polymorphism with strong self-incompatibility and a 1:1 ratio of the long- and short-styled morphs (Barrett, 1978). Monomorphic populations are self-compatible with long styles and a range of stamen heights (Barrett and Shore, 1987).

Phenology

T. ulmifolia produces flowers and fruits all year round (Montano et al., 2011). In Mexico, a reproductive peak occurs during the summer (Torres-Hernández et al., 2000). This species has extrafloral nectaries which are frequently visited by ants (Camponotus planatus, C. atriceps, Conomyrma sp., Crematogaster crinosa, Forelius sp., Pseudomyrmex sp.), wasps (Polistes instabilis and Polybia occidentalis) and honeybees (Apis mellifera) which forage looking for the nectar produced (Cuautle and Rico-Gray, 2003).

Environmental Requirements

T. ulmifolia grows in areas with full sun or partial shade. This species is well-adapted to a variety of soil conditions including alkaline pH and dry sites. Freezing temperatures kill plants to the ground, but warm spring weather brings them back to life (Gilman, 2011).

Notes on Natural Enemies

Top of page

White flies are often found on the foliage of T. ulmifolia and severe infestations of these insects can injure the plants. Aphids and scales can also infest the foliage, but they are usually not too serious (Gilman, 2011). The main leaf herbivore is the caterpillar Euptoieta hegesia (Lepidoptera: Nymphalidae). This herbivore is most active from June to August, although it can be found year round (Cuautle and Rico-Gray, 2003).

Means of Movement and Dispersal

Top of page

T. ulmifolia spreads by seeds, which are dispersed by ants. These insects transport seeds relatively short distances from maternal plants, favouring the establishment of dense populations (Barrett, 1978; Barrett and Shore, 1987; Staples et al, 2000).

Environmental Impact

Top of page

T. ulmifolia is a weed that has escaped from cultivation and has become widely naturalized in tropical and subtropical regions of the world (Smith, 1981; Barrett and Shore; 1987; Wagner et al., 1999). This species has the potential to grow forming dense mono-specific thickets and monopolizing resources principally in coastal areas (PIER, 2014).

Uses

T. ulmifolia is grown as ornamental for its showy yellow flowers that blossom year-round (Montano et al., 2011). Plants are also used as border plants and ground cover (Lorenzi, 2008). A tea made from leaves of this species is used in traditional medicine in South America and the West Indies to treat gastrointestinal problems (constipation, diarrhea), colds and flu, and circulatory problems (heart palpitations), menstrual spasms, and dermatological issues (Gracioso et al., 2002, Montana et al., 2011; USDA-ARS, 2014).
